[TriLUG] How to connect two buildings a mile apart...

not really... just the comment to the other poster about "I didn't realize 
amateur high jinks were the order of the day."  struck me wrong.  I'll 
consider this a failed experiment.  fiber would be nice but the cost for 
right of way not to mention digging under the road for a mile is a bit 
prohibitive.  you kept suggesting frame relay or leased lines... we already 
have that, as I mentioned at first.  I need to go faster than that.  That's 
why VPNs across the Internet or ADSL won't cut it either.

I appreciate all of the responses... really.
