[Blink] Multitrack recording of conference calls

[Adrian Georgescu]

Well,

This can be easily done design-wise in SylkServer used as server side conferencing for Blink, is more than ready to accommodate such feature.  But as always is the kind of super cool stuff that takes weeks or months of develop for which the target few customer will be reluctant even to pay even 1.99.

If anyone knows Python and has time and interest we can guide them to achieve this feature.
