SLP seems to be a good idea for our scenario, here I have some questions:

1.Do we need a centralized server(slpd) to track service or every host 
will have an slpd installed and can handle request?
2.How do we define peers--Even some hosts have kimchi service enabled, 
they are of different hardware/software which prevent them from migration.
3.Do we support peer discovery between hosts which located distantly 
with each other? Will the peer query time consuming?
4.What are kimchi peer discovery's use cases:a. migration, b. browse 
other hosts from one access point, c. others?
