Gambit Tiger just finished 19ply at just under 13 hours . If i'm right this would take 30ply to solve #9 2302911hours or 95954 days 15 hours on an 800Mhz Athlon maybe i'll put it in my will for my great grandchildren to post the result here on CCC in 262 years. let's take into account moore's law 8290479600 seconds after 15 doubles or 270 months 22and a half years 253005seconds 4216min 30 sec or 70 hours if we take this into account from the fastest hardware available now Dual 2Ghz P4 Xeon or 2000x 1.7 3.4Ghz 3400 /800 4.25x faster than my 800 8290479600 / 4.25 = 1950701082seconds after 13 doubles or 234 months so 19 and a half years more years we can solve this around 238122 seconds 66hours with the newest hardware 27852800 27Thz but this isn't taking into account better transistor design /memory etc so within 10 years maybe
