[FOSDEM] Late Arrival to Keysigning Party?

Hello. Anybody minds if I arrive late to the keysigning party, e.g. by about 30 minutes? Is it generally possible? Previously, I was always joining from the beginning, but this time I have my talk overlapping slightly with the beginning of the keysigning party. I do not mind if I get fifty signatures less or so. AFAIK Zimmermann–Sassaman protocol is quite ok for that besides the group check of the hash of the key list file. But, I will be quite convinced that it matches if I do sufficient number of random comparisons with what other people have. Then I should be able to squeeze in the circle and finish the rest of the verification. Hope nobody objects that and I did not overlook any security or other implications. Anton.
