Yes, you do.

Don't forget to instantiate the TMemoryStream as well:

    DataSocket *Data = new DataSocket;
    Data->Proxy = 0;
    Data->MemoryStream = new TMemoryStream;
    Socket->Data = Data;

And then free everything in the OnDisconnect event:

    DataSocket *Data = (DataSocket*) Socket->Data;
    Socket->Data = NULL;
    delete Data->MemoryStream;
    delete Data;

I would suggest taking it a step further by adding a constructor and
destructor to the struct:

    struct DataSocket
    {
        int Proxy;
        TMemoryStream *MemoryStream;

        DataSocket()
        {
            Proxy = 0;
            MemoryStream = new TMemoryStream;
        }

        ~DataSocket()
        {
            delete MemoryStream;
        }
    };


    OnConnect:
        Socket->Data = new DataSocket;

    OnDisconnect:
        delete (DataSocket*) Socket->Data;
        Socket->Data = NULL;

Yes.  In other events, you'll have to cast the Socket's Data property in
order to access the struct:

    DataSocket *Data = (DataSocket *) Socket->Data;
    Data->...

You have to free everything you allocated in the OnConnect event.
