OK. Well I would rather make something generic. Besides, wasn't there 
some MS patent issue? The last thread on the subject that I read kinda 
made it sound like you were going to look into the issue and respond. 
Maybe I missed the response; there's a lot of mail in the archives for 
this list.

In any case, I'd rather just make something more generic that perhaps 
can be used with NBD.
