You can host on dropbox for free until you hit some bandwidth limit (which if you do, I think you can afford to pay for a host or to upgrade the dropbox package).
I think the next thing is for mochi ads to get HTML5 support, I asked them and they said they only do Flash. Kongregate apparently only allows mochi ads or something like that. And of course for more portals to support html5. And of course an fgl equivalent (or official fgl support for html5).
Still I think it's a good first step, very easy to make a few cents <img src="smileys/smiley1.gif" border="0" align="middle" /> on Kongregate now (I didn't hit my target of $1 yet <img src="smileys/smiley17.gif" border="0" align="middle" /> but with the next game I surely will exceed it). Then it's just a matter of scaling a few orders of magnitude until I quit my job <img src="smileys/smiley4.gif" border="0" align="middle" />. I will get there, with C2 or some other game maker (the infrastructure for Flash games monetization is well established, and very tempting...)
