This is what I've read on the BDB glitch-- It is supposedly caused by either someone joining or leaving a game in progress-- so if we get 4 players, nobody gets dropped-- it should keep everyone in the game (no one can join if there are 4 players).
The one session I got through yesterday had 4 players in it-- I had a problem with griefers in almost every session before that-- one team member was blowing up cars, in another the heli pilot flew out to sea, jumped out an exited, one set Friendly fire on and was killing everyone, etc... evidently Saturday night is griefer night... I did have my team get though another session-- but I got killed.

as long as everyone has good connections (Spuds would use his wired connection for this--- I played 6 hours yesterday with no drops)
Realize that getting the coop trophy we would have to do each in the time allowed-- a challenge in itself-- I've only managed the "noose" time....
We could get the win all game modes trophy-- but it would take a while (about 2 hours)-- for this-- start with BDBII (in case we encounter the glitch) and just work up the list--would need at least 3 players for this-- and this would take around 2 hours for one "team"-- each person would have to win in each single player mode
The team trophy requires you to win each team mode-- Team Cops N crooks (win as both in one session), Team Death match, Team Mafiya work, Team Car Jack City, and Turf war.... doing 10 minute sessions both teams could win this one in under 2 hours- one team could do this in under an hour.
For the top of the midnight-- me and sureshot had and issue with the others getting into a game about 1/2 way through-- makes it a bit harder
Whoever is getting the trophy can't leave MP-- so the host should not be the one getting this trophy-- I had sureshot leave and send me an new invite at one point-- we had like 10 or 12 people end up in our race-- they stayed through some heli races too.
Have we tried doing a private match yet?? I've never tried hosting one of these yet-- would certainly make it easier to keep out intruders and speed this along-- me and sureshot were going through these pretty fast before others finally got in our race.
