Why not modify urlencode to explode dict values into multiple instances if
the value was a list or tuple instead?  Example:
    {"x": ["y1", "y2], "u": "v"} ---> x=y1&x=y2&u=v
The resulting urlencode would look something like the following lightly
tested code:
"""
from urllib import quote_plus   # added by PSST
def urlencode(obj):
    l = []
    for k, v in obj.items():
        k = quote_plus(k)
        if type(v) is types.StringType: v = [v]
        for i in v:
            l.append("%s=%s" % (k, quote_plus(i)))
    return string.join(l, "&")
