I don't know but these are my thoughts:
1) agree, think they said next week but not sure
2) agree with getting ryushare unbanned on many forums
3) New paygate should be ready soon as far as i am aware. egatepay.com is good and is used by the big boys (filepost, uploading, fileserve etc)
4) Agree, my sales are awful , really awful - either people are no buying or they are not counting
5) I think rebills occurs on an account basis ? so should work but i don't know
6) If it aint broke, don't fix it - I do not think there is any need for a new script myself.
cheers
