I have added two hypercalls, lv1_peek and lv1_poke. peek reads memory in real space(including all the MMIO), poke writes it. I can also add other arbitrary hypercalls as I see fit.
The hypervisor is complicated, it is written in C++ and is PPC, which I am not that familiar with yet.
Some people have criticised GeoHot as he hasn't yet accessed the isolated SPEs, he replied with this:

Some people pointed out that I have not accessed the isolated SPEs. This is true. Although as far as doing anything with the system, it doesn't matter. The PPE can't read the isolated data, but it can kick the isolated SPEs out. Decrypt the PPE binary you need using the intact SPE and save the decrypted version. Kick out the SPE, and patch the decrypted version all you want. And interesting note, by the time you get to OtherOS, all 7 working SPEs are stopped.
Despite this, he is working on the isolated SPEs now, which he says he can now load.
I suggest you keep your browser locked and loaded at Geohot’s PS3 blog. It'll keep you up-to-date on this very interesting peice of developing news.

3 years, 2 months, 11 days…thats a pretty secure system.
