Just to let you know, Cxom hasn't replied, nor has he opened the PM I sent him on MP Forum. It's still in my outgoing folder.
I haven't seen him on IRC either for a long time.
Starting another project isn't a bad idea. I won't be the one to do it though.
My advice would be to do something less ambitious though, with maybe a dozen builders at most... and put in safeguards in place to make sure the project can be completed even if one or more participants isn't able to complete their parts.
