Re: enterprise vc, I am still horrified whenever I think about the "diff tool" one of our top consultants from Big Blue used when coding in Java: copy code from IDE into Word, copy the Word file across systems, reverse the process...<p>As for what you guys are doing, it's fantastic and it was high time someone decided to tackle the problem. Another huge market opportunity is an editor tailored for writers (academia, fiction, etc), with vc embedded and an open format behind the scenes (HTML maybe).
