[h323plus] Socket aggregation not yet implemented on Unix?

Hello, I have tried to compile H323Plus with Signaling and RTP aggregation, so I assumed that I needed to compile PTLib with socket aggregation first using "./configure --enable-sockagg" However, during the PTLib compilation I receive the message: "aggregation not yet implemented on Unix" Is there any ETA about this feature? Also, is this feature fully available on Windows? -- Best regards, Vlasis Hatzistavrou.
