No rush Mat.
Just my thoughts. If it is a rewrite, perhaps with a configurable section of the script so each user can adapt it. Possibly with different flash templates.
ie, select template type/size, enter database details, and paste code into wherever you want it to display.
That probably sounds like a load of work, but I would guess a few people would find it very useful, and therefore likely to pay for it?

As I said earlier, the thing for me, is making it possible to display the recent vids, from a different domain. Essentially a remote banner advert.
Perhaps sticking a small link to yourself in the code? One of the pages I would put it on is google PR4, along with quite a few PR3's as well. Could be a useful way of climbing the rankings?
