Hi chrisell
I recently took part in a Q&A session on RSC's facebook page, and i asked about them sorting out the DVT issue and implementing it into the core, and this is the answer that i recieved:
'We certainly have the technology to do it and we have been playing around with the idea for a while now'.
Now, this miffed me a little bit because surely with us having WCML-N and now SECML, DVT capabillity is a must, especially for WCML-N?? My next question to them was going to be 'if you 'certainly' have the technology, then why have you not implemented it'? I didn't bother!
Anyway, my point is maybe it would be worth dropping RSC an e-mail (if you have'nt already!) and asking them for some help and/or guidance, although from what i can gather from poster's on these forums, e-mailing RSC is like going to the toilet whilst faced with a severe gale!

But......you never know!
Cheers
