Hashtopus - distributed solution

[Znerox]

Will Hastopus be able to keep track of which combinations have already been tried? For example, if I'm doing an 8 lowerchar mask attack, then 8 char alphanumeric, will it skip the combinations that consists only of lowercase characters? I'm thinking it will have to keep track of that data anyway, since it hands out just 5 minutes of work to each client at a time.
