If you don't want to get involved with locales here is a function that formats numbers:

def int_format(value, decimal_points=3, seperator=u'.'):
    value = str(value)
    if len(value) <= decimal_points:
        return value
    # say here we have value = '12345' and the default params above
    parts = []
    while value:
        parts.append(value[-decimal_points:])
        value = value[:-decimal_points]
    # now we should have parts = ['345', '12']
    parts.reverse()
    # and the return value should be u'12.345'
    return seperator.join(parts)

Creating a custom template filter from this function is trivial.
