I would say do it.
Of course as with most things there will be plus and minus reasons for doing it, but I believe that in this case the plus will out weigh the minus.
As Snake said, he doesn't even have a video, so a conversion to either DVD or download would be needed for furture generations of sploshers, and to keep this amazing material alive.
I know that Messyfun had (propably still do) a download section that had clips from there videos. Aquadisiac, also have a wet clips and messy clips section on their website and have dowloadable clips for ,'A Nightmare on Gunge Street, True Slime, The Muckanic, and various others.
There is of course the time converting, but I'm sure it would be worth it and pay in the end.
With the PC/Mac becoming mainstream and now classed as a piece of furniture instead of business tool, the future looks to be downloads, just look at the poor audio record/CD.
Also, while I'm on a rant, I can remember I previous post I did about the Splosh magazine in PDF format.

So that would a great idea also.
