Multiple TFTP and PXE servers on same subnet--possible?

We currently use Symantec Ghost Solution Suite 2.0 and the 3Com PXE CD to be
able to clone our computers, booting via PXE. This is setup on our special
cloning subnet, and, works fine.

In our agency, we have multple Wyse bricks (TS/Citrix thin clients), and use
their Rapport program, which also uses TFTP and PXE, to push an image (made
with Rapport, not Ghost) out to them. This is setup to work on the subnets
that we have the bricks on, and, also works fine.

We need to expand the subnets that Ghost will work on, and, this will
involve it and Rapport being on the same subnets.

Is there a way to do this? Can these two separate systems co-exist on one
subnet? Can I just use one of their TFTP and/or PXE servers to provide info
for both?

Thanks!
