[H-GEN] SETI at home

[Michael Anthon]

(Note reply-to: being general at humbug.org.au vs Michael Anthon <mca at tams.com.au>)

Although I would dearly love to participate in this, the volume charges
really are a killer.    I would really like to get a real figure for the
amount of data I'd be chewing up.  Rob, how fast does the K6-233 you
mentioned process RC5 blocks?  My machines are currently doing about 5,500
kkeys/sec overall and I'm wondering what this would translate to in $/month
if I switch to seti at home.

Umm... without checking if my maths is right, it be something like 
$/month=(5500/k6-233-rc5-rate)*356000/1000000*0.19*30  [1]

Cheers
Michael A.

Not guilty, your worship.  That comes under "more efficient format"
because IIRC the data is base64 encoded.  It still seems like a
worthwhile feature request.
