This assumes incompressible fluid flow, which isn't a very good
analogy for typical web data traffic.

OK. You got me there. You're not supposed to take it too
literally !
I was trying for an analogy to express the fact that by ganging up
users you get a combining effect. For example, if one user needs a
"700 kbps" connection for a "high-speed" feel, 6 users don't need 4200
kbps, but will have a good experience with 1500. Of course, I'm
talking about the touted "up-to" speeds. The delivered speeds are
often 1/2-3/4 that.



I sorta help with 3 different systems that share a satellite link. All
are HughesNet (DirecWay). The planned Wild Blue system fell through.
The problem is that all 3 of these have DSL or cable available within
wire or wireless range. However, they all have also successfully
precipitated a war with the neighbors making a wired or wireless link
somewhat problematic. I've been elected official diplomat and am
trying to negotiate a peacful compromise that will allow them to
obtain a terrestial alternative. However, no sooner do I obtain some
sort of verbal agreement, someone always manages to restart the
battle. I'm scheduled for yet another non-billable endless debate
this weekend. Sigh.


Um, political problems. Another can of worms. As we all know,
satellite is only for those who can't get broadband. Or even medium
band. But it's better than dial-up still. Unless/until you hit FAP,
that is!

I've suggested getting wider bandwidth connections. One of these has
just done that. I haven't seen the results. The others are still
waiting for me to "somehow" provide them with a terrestial solution
and therefore don't want to invest in a 1 year HughesNet commitment.

I think that they will like it better. And with the new FAP, it may
make the critical difference on being able to watch youtube,
whatever. Of course, if it's a bad installation or small-dish, then
it may not help the speed. My experience is that the real difference
is going to the 2-watt transmitter and big dish acounts. I think you
get priority as a biz class user.


Still won't help for VoIP or VPN no matter what account you have.

Yep. Physics can only be overcome by politics.

Huh?

Note: FAP for Hughes net is extremely complex and had just changed
this month. Also, they are not disclosing any real numbers. Look to
the sat forum for more info. http://groups.google.com/group/alt.satellite.direcpc/topics?lnk=li&hl=en

Ouch. I hadn't noticed. Kinda reminds me of trying to come up with
the ultimate fair equitable and manageable ISP billing system. Little
wonder the industry has almost universally gone to flat rate. It's
really difficult to be fair and equitable.

I'm wondering when they will start selling bandwidth like
electricity. Especially on Satellites where it's so expensive for the
providers to acquire. Put a meter on the sucker and charge by the
gigabyte. Then they will need no FAP. Problem is, I think that most
users consume very little bandwidth and are subsidizing people like
me. And the bigger bandwidth users would drop way back if they had to
pay what it really costs on Sat.

I suppose that just like electricity and water, you simply charge a
minimum fee for the connection and then charge usage for anything over
that.
