Ask HN: Would you be interested in HTML to EPub as a service?

[heeton]

We needed to create EPub documents, and couldn't find a service anywhere to handle this, so we made our own. Would anyone be interested in that? If it's really needed, we could make ours into a public service.

Yes - Though, I thought one could use Calibre for this with a regex. But, at least for me, it was very error prone.
