I don't think so, because each company would have to record the fair market value of the service, i.e the company farming the silk (with all costs) as a deferred revenue and our Company as amount owed to a supplier. The only way that I see right now is that UND having such arrangement as a major share holder (which would have received shares in exchange of "services", where the "service" is to pay for the farming of the silk) but maybe I'm stretching it...
I think that this sort of thing is possible (silk farm carrying costs til profit) but you are perhaps making it too complicated.
It is the normal mode of business to business to sell things "on account" where payment is not due for 30 to 90 days.
Also, for a start up with a new unproven product (the MS worm) it would simply be good business for KBLB to offer their eggs to a silk farm with a contract to pay a certain amount only If and When the worms have spun truly and the farm has sold the silk at a profit higher than normal B.Mori silk.
This would be a good business practice to establish KBLB as a premier supplier and would incidentally result in reportable revenue for KBLB after 60 to 90 days.
