Yes - discussion at the next WWG is desirable - it's now on the 2/12/08
agenda.

W.r.t. porting OFED/Linux apps, consider current openSM and future
openSM enhancements which currently are a royal pain to get into the
Windows world. OFED Infiniband diagnostic are another large set of
programs which are desired in the Windows world. Although OFED APIs are
not 'central' goals of the WinVerbs design, there are indeed very useful
OFED userspace applications which really do not need to be completely
recreated for Windows. 
Compile-n-go is likely a non-started although reducing the porting time
could be a huge win for many.
Should I also mention those 'user' constructed IB applications which
just might be desirable to interoperate between Linux and Windows?

Looking forward to ongoing discussions here and at the WWG meeting.

Stan.
