Yeah, it is almost ready for an alpha snapshot now. I have abandoned the compression map -- it consumed quite a lot of vmalloc unswapable kernel memory. ftape/zftape now allowes for tapes up to 2^10*2^31 = 2^41 capacity. This is 4GIG times 512 which should be plenty even when using compression. There are also some minor bug fixes.
I hope to release an alpha snapshot soon, will announce it in this mailing list.
Cheers
Claus
