Not sure about that, but it is my understanding that PC boxes tend 
to be lacking in hardware contexts, which is directly related to the number 
of processes (i/o streams???) that you can run concurrently.  Now, since 
it's online, you can comment about 1/3 <?> or so of the daemons out of the 
rc files and save some processor and process numbers there.  I mean, why 
does someone dialed in need to use lpd, except as a security hole?
This is assuming you aren't using the machine as your primary box, or 
something...

I believe there exists software to turn a PC/ DOS with 2 network cards into 
a router.  This may not be the best solution; the machine costs money if it 
isn't already lying around (and who can't find a cheap 486 with a small HD 
and mono VGA?) and if the software isn't PD that would probably put over the 
top in terms of expense....just a possibility.

Well, actually I was talking about a T1.  We were quoted, for a T1, twice 
the price of a 56.  Then there is 30x the bandwidth (56kbps v. 1.54 mbps) 
and alot of room for growth.  You have to figure-- If we had to go to t1 
from 56, we would have spent enough in installation just to get it to begin 
with-- same story with 2 56's.  Then you have spent enough for a T1, and got 
one fifteenth the capacity...

If you mean a SLIP/PPP connection by 28.8 modem....not bad.  Installation 
from your point of view should be minimal.  Hell, as far as that goes, 
multiple 28.8's might be a possibility if your service provider wasn't so 
steep... Just remember; once you've got a cable strung to your house by 
Ameritech or whoever, you gotta use that line for quite some time to justify 
the installation costs....and then you gotta have a machine to use all the 
bandwidth.. Catch-22.  Gotta have the most bang for the buck on line 
charges, then you end up having to grab a machine that can handle hundreds 
of connections at once, and then.......

Sorry for the diatribe.  Just working out some frustration :)

How many providers are in your area?  At least a few with POP's around here.  
Some of them have crappy rates.  Shop around if it's at all possible....

Update me how the bit with the 28.8 modems go....I have heard inconsistent 
stuff about Rockwell and Hayes 28.8 serial flow.  Something about not being 
able to do DTE/DCE speeds over 38.4 or something...
