very well. I think quite a few people would love to see this in Inkscape.

not yet. The main purpose of my email was to discuss the best method to
do this. I guess if you plan to integrate it, I should create an
embroidery branch on launchpad, which means I would need permission to
do so. I should say that I have close to 0 experience with bzr, but
quite a bit with git and before with SVN, Clearcase & Co.

If you first want to check if I do reasonable quality code, I can of
cause upload a patch e.g. on my website.

In case you want me to start on launchpad right away: my launchpad
account name is MSoegtrop.

Best regards,

Michael
