No problem.  I should have figured there was a method to the madness as 
they say.  In that case you're already requiring the Linksys, so go for 
it.  As someone else already mentioned, there is a separate setting for 
each optional interface for dhcp, but that would essentially require that 
you have a separate interface for each office.  That is probably a good 
choice if it's physically feasible, but on most hardware I'd expect that it 
would require multiple NIC cards.  I don't know which if any of them are 
supported.  That would be much more secure since it would prevent anyone 
from sniffing packets on another subnet since they're no longer physically 
connected.  It does however restrict how many subnets you could offer.  It 
may be a reasonable solution though, and certainly worth investigating I 
would think.  Assuming that you're charging these other offices for 
connectivity, etc., any additional cost for the NICs and possibly different 
hardware could easily be justified and passed along as required.
