* Haskell implementation?
* Optimizing for space and reliability: Sharing catalogs and availability
* Draft desired API
* Implement current meshboard with [[Tubes]]

== Notes ==

API: ? FUNC: store 10k of a 1m file for the community

''on State''
'''State''': M_ij - connected? dropped? new?
--> store trafic/cache state, draw pretty pictures

Move guys around
Create and query objects [KNOBS?]

''algorithm''
Resource::Ad/Music/Pix/SW
Add:: Post/Make-available

(1) '''Add''': Store locally
Create handle ==> UID [hash?], summary [thumb, precis, author+date]
summary lets them do local search without having the whole thing
Each peer asks for others' handles and with some probability the actual resource
probability depends on size, popularity, space, other; compare <tt>Time To Leave</tt>
Q: poll v. push?
recipient has final say, including cache & expiry
(2) '''Retrieve''': Compute query
for all peers, send query (peer remembers Q). [if local, maybe punt, else search for more]
for all new associations, send Q [timeot?[]
at some point, Q --> H or R [done]
given H, for all peers, send H [store if found]


''open questions''
* how to order reqs for pieces -- first part of a web page first?
* how to retrieve/split up a large file into many pieces? lockss, filenets.

The MeshBoard activity is a way to share requests for and offers of content, services, or anything else. It currently uses an xml-rpc server as part of the activity, to work on all sorts of networks; but is being updated to use the mesh and presence service.
