| 35 | 14 | Adrian Georgescu | |
| 36 | 14 | Adrian Georgescu | |
| 37 | 15 | Adrian Georgescu | After analyzing candidate libraries *Wokkel* was the chosen one for the following reasons: |
| 38 | 15 | Adrian Georgescu | |
| 39 | 15 | Adrian Georgescu | * Implemented on top of Twisted, which makes integration with SylkServer straightforward |
| 40 | 15 | Adrian Georgescu | * Support for both component and XMPP server models, allowing for flexibility in implementation |
