regardless of (potential) design problems, i'd like to try to discuss 
your problem.
i hopefully understood you right... you want to read and write 
arbitrary/binary data in some sort of queue (array?)?
as i read your explanation, two things came in my mind:
*the Memory keyword: http://gambasdoc.org/help/lang/memory?v3
*the Struct keyword: http://gambasdoc.org/help/lang/struct?v3

i never worked with either of both, but you can define functions for the 
Memory solution to read and write your structure, or create an array of 
your defined structure (but those, i read, do not have e.g. an Add 
method, so you'll have to implement it yourself, maybe...)
i just noticed, since struct arrays are embedded arrays, the two 
solutions will lead to the same in memory, i think, but are different 
ways...
(i still hope, i understood your problem)

(btw, there's one thing that makes me stuck apart from the network 
related design: the term "player" made me think of a game, so you want 
to have a game in a network and you said that you want to resend data 
which may not even be "up to date", so why resending that and not the 
current data? but that's something, that depends on your game, i think...)
