Re: [Manet-dt] Question and Comment on OLSRv2-03

Dear Kenichi,

Thank you for your comments and apologies for the slightly belated  
reply. As I am sure you have noticed, we have reissued NHDP taking a  
lot of the comments provided by Owada-san, Satoh-san and others into  
account, and I think included also clarifications on the comments you  
have below.

Regarding OLSRv2, we have been putting that a bit on a side, with the  
objective to get work done on packetbb and nhdp, which we want to get  
completed ASAP. Your comments on OLSRv2 are noted, and we will get  
back to you on those in short order.

Thank you again for your comments and corrections,

Thomas
