If you open an issue, we'll look into it. I can't make promises regarding time lines though, we're stretched pretty thin. If you're backed by a company, you may want to talk to our support people. We're not really in the business of bespoke work but this is general purpose enough that it could be done on a contract basis. If you're interested, let me know and I'll get you in touch. -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
