I would absolutely love to do this. But it's going to be very difficult - toeing a line between trading while insolvent, keeping suppliers on board, and trying to recapitalise an unproven business. There are plenty of distressed investors / turnaround funds out there - they tend to focus on established businesses and even then often struggle to achieve a positive outcome.

However, I do think there is scope for a sort of holding pool for products that are acquihired and then shut down. Eg. Posterous would be a good candidate. Let the staff go to their new homes, but build a team whose specialist skillset is in taking an already built product, putting it into stasis and dropping ongoing costs, and then monetising that existing tech/content/audience/userbase. Perhaps in the hope that some later startup can use the existing product to build-off in return for equity.
