Cliff,
     .Net objects can be accessed via the COM interface, and it's a
good way to use it.  The down side (and it's a really big down side..)
for the COM interface, is that (if I'm recalling this correctly, it's
been awhile) a non .Net program calling a .Net class has the same
triple call overhead that a .Net app has calling a non .Net class.
Literally there is a three call overhead for each time you call from
one to the other.  Not a problem if the class you're calling is doing
all the heavy lifting, or you need a quick and dirty solution, but
nasty for a lot of things.
