My vote is to ride it, I currently run one on an old cannodale beast of the east frame with those goofy aluminum flatbar rear dropouts that stick straight out the back like three inches, i've kind of been waiting for them to snap off but they seem to be holding up ok.
For you I think if anything was to fail it would be the epoxy joint at the seatstay yoke if during manufacture they didn't stuff enough epoxy up against the seat tube. If it did fail it would be more of a comedic type of failure as you slowly pedaled into the ground, not the dangerous sudden fork snapping type of failure. So, one vote for do it!
I don't think the drops are all that likely to blow, but the rest of the loads are going to the chain stays, and will be compression loads that carbon doesn't like, so how strong that area is on your particular bike would be critical.
I think a better bet would be an ad in Craigs for a cheap or free donner frame of steel.
