Currently there are several topics in the VtES Usenet Newsgroup where VtES players discuss the issue of self-ousting in the game. There some (but in my opinion not too many) situations in past games where this was an issue, and therefore I am not for any radical changes to the existing rules (including the rules changes that have been proposed in the newsgroup, although I haven't read all of the posts).
Personally, I would just like to see a little rule additions in the game. That is, that you cannot deliberately reduce your pool to zero (or less); that is a player cannot transfer out himself, or pay cards that would cost him all of his pool. Yes, there's Dragonbound, Army of Rats, etc. as "loopholes", but in the end some other player has (or had) to take a deliberate effort to oust the player in the "lost position" (whatever that exactly is). This might only result in an additional full round around the table (or more likely somewhat less), but this can still make a difference for course of the game without changing the rules radically.
The proposal of the other participants in the discussion are often too complicated and/or require the intervention of a judge (e.g. to declare whether a player is a "lost position" or not). Both alternatives are not really acceptable for me. And in the end, you cannot really prevent people from being idiots, morons or just suicidal in the game with a written set of rules.
To get an estimation, what the players think about the self-ousting issue, I have created a poll with some basic opinions about self-ousting in VtES.
