I've mostly been on the Reddit end of this discussion, may be good for reference:

The next step is reaching worldwide keyboard manufacturers so a BTC symbol is added on keyboards
A lot of these steps would follow more naturally from the inclusion of a symbol in the Unicode specification. I'm not sure keyboards would be a priority, though obviously there would be a market for keycaps

I think one of the first steps would be mostly to approach developers of popular online editors to include an option to insert the Bitcoin symbol (if not readily available through a generic 'insert special character'). The W3C should also be approached to add e.g. &bitcoin; or &btc; or &xbt; (depending on argument) as a parallel to the € HTML entity. These are quite separate processes though

Interesting idea, and a needed one i believe, because other than here on btctalk, we can't make btc symbol right now.
It's actually a lot easier to insert the symbol than many people think. We've added it to the Bitcoin Wiki in the same manner as has been done on BitcoinTalk, for example.
I have added a section on
inserting the Bitcoin symbol to the Bitcoin Wiki. There's at least 3 approaches that are all reasonable to implement (if anybody knows of more, shoot me a PM or edit the Wiki directly; don't want to clutter up Ken's thread). Some of it could even be automated with a script (run through document, search&replace "BTC" with the symbol).
Having it included in the Unicode specification does mean that all of these workarounds can, eventually (keep in mind that fonts will need updating), be dropped in favor of just inserting the symbol, fitting with surrounding text in every which way, which is much more desirable.
