A pink sheets market is possible with bitcoin but you need qualified financial brokers doing it not the general public, since only qualified financial advisors can hold stock broking licenses. You cant sell shares directly to the public as all of the bitcoin stock exchanges currently do and this is where the problem begins.
Does this mean that unlike the proliferation of forex sites, there are no sites I can go to and just buy myself some stocks/shares without having to get ahold of a broker in chat or email or something and chat with the broker about my needs so the broker can decide whether they consider me a fit person to sell stocks to?
I do like the idea of brokers actually as a person who runs one or more Open Transactions servers. It seems to me it would be great to have brokers to point at any time anyone claims Open Transactions is "not for grandmothers" and tell them hey go get one of those brokers in videochat tell them what you want send them money and whether they use Open Transactions or the New York Stock Exchange or the Toronto Stock Exchange or an Excell spreadsheet is all on their side not yours, you just talk to the nice broker and dont' worry your head about those kinds of details...
