Sorry if I missed something but is the issue with eligius resolved?

don't know if this is worth your time, but since this will become an increasing problem over time maybe it is worth some thought. Maybe you can have a bundled auction of accounts that have low dividends. That would just be one auction for you to handle, you can charge a fee for your time if necessary, and the proceeds can go to payoff the smaller accounts. This way those accounts get closed out fairly rather than having dividends disappear and it gives an opportunity for others to increase their holdings.

For example, the total number of shares held in all accounts with <145 shares is 3204 (~1% of the total share count). There are  57 out of 209 accounts with < 145 shares (27%). Bundling up and buying out those accounts will stave off worrying about dust and simplify management of the group buy. One one hand, only 1% of the total number of shares are effected. On the other hand, more than one quarter of shareholders would be bought out.

I think selling 134 GH/s of currently hashing, no pre-order, no hosting setup, would be an attractive offering.
