Perhaps it is useful to summarize reasons why toolserver users are not able to change to tool/bot labs. I added my main reasons. Perhaps other can add their reasons, too? (Mabe we should also add this list to the wiki page)
temporary blockers * no replication of wikimedia wiki databases ** joining of user databases with wiki databases * no support for script execution dependency (on ts: currently done by sge) * no support for servlets
missing support blockers * no support for new users not familar with unix based systems * no transparent updating of packages with security problems/bug
permanent blockers * license problems (i wrote code at work for my company and reuse parts for my bot framework. I have not the right to declare this code as open source which is needed by labs policy.) * no DaB.
