Has anyone constructed Summon API queries in javascript?  (assuming that they can be constructed to use jsonp and avoid cross domain problems …???)

If it helps, here are a few lines in python that I use to make summon queries:

def summonMkHeaders(querystring):
            summonAccessID = 'yourIDhere'
            summonSecretKey = 'yourSecretHere'
            summonAccept = "application/json"
            summonThedate = datetime.utcnow().strftime("%a, %d %b %Y
%H:%M:%S GMT")
            summonQS = "&".join(sorted(querystring.split('&')))
            summonQS = urllib.unquote_plus(summonQS)
            summonIdString = summonAccept + "\n" + summonThedate +
"\n" + summonHost + "\n" + summonPath + "\n" + summonQS + "\n"
            summonDigest =
base64.encodestring(hmac.new(summonSecretKey, unicode(summonIdString),
hashlib.sha1).digest())
            summonAuthstring = "Summon "+summonAccessID+';'+summonDigest
            summonAuthstring = summonAuthstring.replace('\n','')
            return
{'Accept':summonAccept,'x-summon-date':summonThedate,'Host':summonHost,'Authorization':summonAuthstring}
