There is no need to do it through writing and reading files. Beanshell extension mechanism is smart enough to handle it without interim 3rd party entities.

Short answer: bsh.shared namespace

Long answer:

assuming following Test Plan Structure:

Thread Group 1 
    Beanshell Sampler 1
Thread Group 2
    Beahshell Sampler 2

Put following Beanshell code to Beanshell Sampler 1

Map map = new HashMap();
map.put("somekey","somevalue");
bsh.shared.my_cool_map = map;

And the following to Beanshell Sampler 2

Map map = bsh.shared.my_cool_map;
log.info(map.get("somekey"));

Run it and look into jmeter.log file. You should see something like

2014/01/04 10:32:09 INFO  - jmeter.util.BeanShellTestElement: somevalue

Voila.
